Specification of Letters Patent.

Patented Jan. 3, 1911.

Application filed September 9, 1810. Serial No. 581,264.

To all whom it may concern:

Be it known that I, PATRICK D. RIORDAN, a citizen of the United States, residing in the borough of Manhattan, in the city, county, and State of New York, have invented certain new and useful Improvements in Snow-Destroyers, of which the following is a specification, reference being had to the accompanying drawings. 7

This invention relates to improvements apparatus for destroying snow; and an object of this invention is to provide an apparatus of the character just referred-to which will be comparatively simple in construction and which will be most eflicient in use.

Apparatus to improvements. in which this invention relates find their widest field of usefulness in lar e cities from the much traveled streets 0 which the snow must be speedily removed to the end that trafiic may not be impeded. In such cities water is supplied to hydrants at street corners or other convenient points along the highways for the purpose of affording protection in case of fire. In carrying out my invention advantage is taken of this provision of water under pressure by equipplng my new apparatus with means for supplying water to the snow; and, in its preferred form, my new apparatus is fitted with mechanism for 'triturating the snow and this triturating mechanism may be driven by water flowing from the hydrant. The snow-destroying mechanism will be mounted upon a vehicle; and this vehicle maybe self-propelled, the propelling mechanismbeing adapted to be thrown into and outv of engagement with the mechanism which drives the snow-destroying machiner An engine, however, may be used to drive the latter and the exhaust from this engine maybe led to the same so that the heat iof the exhaust may be used in reducing the snow to the form of water. Since the water flows through the apparatus at a high velocity and is constantly agitated by the triturating devices, there is no danger of the apparatus'becoming clogged due to freezing.

Other features of this invention Will be pointed out in the detailed description which follows. i y

In the drawings illustrating the principle of this invention and the best mode now known to me of applying that principle, Figure 1 is a central longltudinal sectional view through my new snow destroyer, the engine mechanism being shown in full; Fig. 2 1s a top 1plan view parts being broken away for c earness of illustration; Fig. 3 1s a bottom plan view; Fig. 4- is a detail showing the opper disintegrator and conveyer on an enlarged scale; Fig. 5 is a detail showing the manner in which the knives .of the disintegrator are fastened in place; Fig. 6 is a detail showing in top plan view the lower ard-rod supporting-rlng; Fig. 7 is a deta1 of a; grating hereinafter described; Fig. 8 1s a detail in perspective showing the ribs of the grating of Fig. 7 inverted and edged at the bottom; Fig. 9 is a section on the line AA of Fig. 1; Fi 10 is a detail in perspective of the sweep s own in Fig. 9; Fig. 11 is a detail in pers ective of the knives of the triturator an their mountings; Fig. 12 is a detail which shows in cross-section a knife of the triturator; and Fig. 13 is a detail showing the manner in which the triturator is mounted in the tank. The apparatus as a whole is mounted upon and is carried'by a truck-frame or chass1s a which is, in turn, supported upon the axles b, '6. These parts are, however, shown in only a conventional way and without any attempt at detail, since the particular construction of the supporting road-vehicle is no part of this invention and the best practice in road-vehicle construction will in an event be followed. The vehicle may be sel propelled and such'an arrangement of parts is shown in the drawings, wherein the engine d drives the flexible shaft (1 on the rear end of which is mounted a bevel gear (1" that meshes with the bevel gear e VvhlCh is mounted loose or, idle uponthe-transverse shaft e On the latter are mounted fast a pair of sprocket-wheels c which by means of sprocket-chains c, are connected with the rear wheels 0 mounted on the rear axle b.

The chassis a supportsthe casing or housing f on the annular top f of whlch is fastened the ring m" of a spider m the arms m of which are integral with the latter and connect the same to the hub m" of the spider. To the ring m" is secured the casing g of a water-motor or water-wheel h. The latter turns in a chamber a which is closed at the top by a cover k provided with an air-tight manhole cover is. The bottom of --the chamber 71 is open. since it is formed by the ider-arms m just referred to. The hub m of the spider m serves as a bearing 'the bottom 3'5 a stationary but remova for the hub 7.2 of the water wheel 72- the buckets h" of which ride on rollers h mounted on the ring m of the s ider m. Through a hole in the hub m o the latter extends the up er end of a solid driving shaft n which is vertically and centrally disposed andon the upper end of which is fastened the hub k of the water-wheel 12, just referred to. Around the casing g of the waterwheel 7:, extends a water-pipe oat suitable intervals along which are arranged nozzles p that project inwardly through the casing 9 into close proximity to the buckets h of the water-wheel it. One end of the pipe 0 is connected by sections of hose-pipe q with a suitable source of water-supply, as the hydrant 7'. It is obvious that, when the water under pressure flows through the pipe 0 and is discharged through the nozzles p, the energy of the streams of water flowing from the latter will be expended in driving the water-wheel h and thereby the main driving shaft n.

To the shell-like casin f at the back and near the bottom thereo .is fastened an L- shaped bracket .9 on the horizontal part of whlch is seated and firm'ly fastened in place .by bolts :1: a twoart or split ring t in the top flanget of w ich are fastened, as hereinafter described, the lower ends of guardrods u the ii lpper ends'of which are held in ange 'v of a'split ring '22. The

guard-rods u and the split rings t, '0 form le cage the purpose of which will be hereinafter explained. Wirework 106- may be placed at the bottom of the guard-rods u to prevent the passage of stones and the like. Inside of the ring '0 is seated the lower or baseend of the conveyer-casin y to which the parts of the ring '0 are astened by bolts 10. The casingy rises vertically upward and in it is mounted a helical or screw conveyer a. The base end of the conveyer-casing y is enlarged andis formed with a shoulder y over which fits the inwardly-projecting top flan e 'v" of w the ring v, whereby the base end '0 the con veyer-casing is held rigidly iniplace. The

.- 3 to facilitate the discharge. Furthenthe top 0 of the latter isinclined from the rear slightly upward and a. downwardlydnclined chute 2 leads from the upper end of the con-" veyer-ca'sing to the chamber '5 in t which turns the Water-wheel h, the lower or .dis-

charge end of the chute 2 entering through van opening in the dome-shaped cover 70 and having a flaring or trumpet-shaped mouth chute 2 gradually increases in size from its upper to its lower end to facilitatethepas sage of the snow. To keep the mouth 3 clear and unobstructed, the arms h ofthe' waterwheel h is provided with inclined blades or vanes c" which sweep across the mouth 3 and carry away the snow, which then falls between the arms h*.

Between the lower end of the screw-contweenthe knives'7 are slightl wider at the outside than at the inside 0 the cutter 4. The lower ring 6 is carried by the outer ends of the spider-arms 10 'of the spider 11 and is formed with a central web or bottomplate 12 which closes the cutter 4 at the bottom and is formed with an opening '12 adapted to be closed by a shutter 12". By opening the latter the space above the bottom-plate 12 ma be cleaned out. The outer edge ortion o the lower ring 6 projects slight y beyond the outer edges of the knives 7 and extends under the top flange if of the lower ring t in which are mounted the guard-rods u.

To each side of the chassis a near the rear end thereof is fastened an end of a transversely-disposed bracket 13 near the middle of which is pivotall mounted the lower end of the conveyer-sha z. The lower part of the latter extends through a central opening. in the bottom plate 12 ofthe cutter and lies within a hollow shaft 14 to the u per end of which is fastened the hub 11 of the spider 11 and on the lower end of which is mounted fasta bevel gear '15. A collar 16 on the conveyer-shaft z furnishes a bearing to eeve steady the lower end of the hollow or s shaft 14, which serves to turn the cutter 4 in a direction opposite to that in which the" screw-conveyer z is rotated by the shaft 2.

The latter and the hollow shaft 14 are driven in the following manner: Extending lengthwise of the chassis a is a shaft 17 which is rotatably mounted in hangers 18 that depend from the chassis a. The front end of this shaft 17 carries a bevel gear 19 which meshes with a bevel gear 20 on the lower end ofthe driving shaft n; and the rear end of this shaft 17 carries 'a bevel gear 21 which meshes with a bevel gear 22 on the lower end of the conveyer-shaft z. Mounted in the hangers 18 and above the shaft 17 is the rotatable shaft 23 on the rear end of which are fastened the pinion 24 and the.

bevel gear 25. The latter meshes with a bevel gear 15. on the lower end of the hollow shaft 14, while the pinion 24 meshes with a spur gear '27 on the shaft 17. The bevel gears 19, 20, the shaft 17 and the bevel gears 21,22, transmit the rotatory motion of the main driving shaft n to'the conveyer-shaft a, while the shaft 17 through the spur gear 27 and pinion 24 drives the upper shaft 23 and through-the latter and the bevel gears 25, turns the hollow shaft 14 and thereby the cylindrical cutter or disintegrator 4.

Surrounding the guard-rods u and spaced :1 suitable distance therefrom is the wall of 5 a frusto-conical hopper 28 the bottom of which is formed wit 1 an opening 29 to permit the assage ofthe lower ends of the guard-r0 s u. The ring if is formed at its top with upwardly and outwardly inclined 0 lip it giving to the ring a flarin or trumpet-shaped annular top within which lies the bottom edge of the hopper 28. At its upper edge the hopper 28 is hung in the bracketlugs 30 free to swing on the rear of the cas- 5 ing Extending upwardly and rearward y from the transverse bracket 13 is an arm 31 on the free upper end of which is pivotally mounted a toothed disk 32 which meshes with the spur gear 33 fast on the 0 hollow shaft 14. The upper face of the toothed disk 32 is ribbed or corrugated and upon it rests a roller 34 carried by the lower end of the leg or post 35 which extends downwardly from the bottom of the hopper 5 28. A coil s ring 36 serves to hold the roller 34 firmly against the ribbed upper face of disk 32 and, as the latter is turned by the spur gear 33, a vibratory or shaking motion of the hopper is produced. In this way 0 the snow is shaken down toward the guardrods u and the cutter 4.

Just below the junction of the chute 2 with the upper part of the conve er-casing y there is mounted on a ledge y inthe lat ter a grating 37 the ribs or bars 38 of WlllCll are beveled or edged on the lower face of the grating. The top of the scre'w-conveyer 2 lies in close proximity to this lower face and, should pieces of ice or other hard substance become wedged in between the ribs 38 and the screwconveyer a, they will be crushed into fragments so small that they will pass through the small openings in the grating 37. Above the latter is mounted a sweep 39 consisting of spider-arms 40 which carry hoops or bands 41. These rings 41 carry blades or vanes 42 which, together with the spider-arms 40 are provided with pins 43. The outer ends of the spider-arms 40 are provided with plates or strips 40 This sweep serves to throw the snow into the chute 2 and'to keep the top of the grating 37 clear, as well as to disintegrate or triturate the snow still further. Just above 55 the grating 37 and outside of the sweep 39 there is mounted a semi-circular water-pipe 44 which is connected with the water-pipe 0 and which is formed with the perforations 45 on its outside, whereby the streams or 0 jets of water flowing through these perforations are directed toward the chute 2.

The driving shaft it extends through a hollow shaft 46 the upper end of which turns in a bearing in the hub m of the spider m 5 and the lower end of which is formed with a collar 47 supported in a -ball-bearinq' 48 in transverse girders 49 which extend from side to side of the chassis a. On the lower end of the hollow shaft 46 is mounted a bevel gear 50 which meshes with a bevel gear 51 on the front end of the shaft 23.

The driving shaft 11. and the hollow shaft 46 extend through and are centrally dis posed within the shell 52 of a triturator 53. The shell 52 is formed at its u per edge or top portion with an outward l flange 52' which is fastened in any suitable way to the top f of the casing f The triturator 53 is supported on legs 54 the lower ends of which are fitted in recesses 55 formed in the bedplate 56 which constitutes the bed of the truck. Within the shell 52 and with its ed es in as close proximity thereto as possible without touching the same, there is mounted on. the hollow shaft 46 at the top thereof a screw-conveyer 57. Immediately below the latter there is mounted within and fastened to the shell 52 a horizontally-disposed knife-carrying grating 58 consisting of radiallyextending spider-arms 59, which are formed with re cesses 60 in which are fitted a series of concentric rings 61. At the bottom of the shell 62* another horizontally-disposed knifecarrying grating 62 which is similar in construction to the knife-carrying grating 58. About midway between these stationary gratings 58, 62, there is mounted on the hollow shaft 46 a horizontally-disposed knifecarrying grating 63 which rotates with the shaft 46. In the stationary gratings 58, 62 are mounted the base ends vof the doubleedged knives 64, the knives carried by the grating 58 extending toward the knives of the stationarygrating 62 and the knives of both stationary gratings 58, 62 extending to within a short distance of the rotary grating 63. Similarly, the points of the knives 65 carried by the latter lie within only a very short distance from the stationary grating opposed to those points. The arrangement of these'knives 64, 65 is such that only a narrow interval separates knives adjacent to one another; and in order to prevent any collision between the stationary knives 64 and the moving knives 65 and to hold these knives in place, they are bound with hoops 01'' bands 66. The grating members 59, 61 are triangular in cross-section and an edge is presented by them to the vfalling snow, in order to insure the latters free passage downward.

Between the shell 52 of the triturator 53 and the casing fis arranged the shell or wall 67 of a tank 68 the bottom of which forms a part of the bedplate 56 of the truck. The wall 67 is substantially concentric with the wall 52 of the triturator 53 and its upper edge or top portion lies a short distance be- 'is formed by a 'discharged into a fo'rwardl low thetop f of the casing f. The latter is at its lower portion cut away from front to rear along the lines 69 in Fig. 1, from which it results .that the bottom of' the casing f pair of helically-dis osed surfaces down w Kill the water and nelydivided snow flow fromthe tank 68 and are and downwardly inclined chute 70. Within the latter is rotatably mounted a shaft 71 on which are arranged the blades or addles 72, the outer ends of which lie in a elix described about the shaft 71 as an axis. The shaft 17 carries a sprocket-wheel'73 which is connected by the chain 74 with a sprocket-wheel 75 fast on the rear end of the shaft 71 whereb the latter is driven. The action of the pa dles or blades 72 is to pulverize any snow partlcles sus ended in the water flow- .ing through the c ute 70 and to force the liquid mass to its discharge end. A flexible conduit or hose-pipe 76 cou led to the front endg-(or discharge end 0 the chute leads The top f of the casing f isprovided with door 78 which covers an opening in the wall 67 of the tank 68. at the bottom thereof. By pullin :the slide-rod up so as to raisethe plate 8 above the opening, the liquid contents of the tank 68 will be permitted to flow into the chute 70 and thence through the hose-pi e 76. The wall 67 of the tank 68 is further ormed with an opening 79' p rovided with a cover-plate 80. By removmg the latter, access maybe obtained to the space below the lower stationary grating 62 I of the triturator 53 and'a hook-shaped bar or other suitable implement ma be used to may have remove the solid material whi there collected.

In case the snow in the street is in a melting orslushy condition, the hopper 28 may be detached from the" bracket-lugs 30 and lowered, after removing the le 35 and spring 36, so that its lower edge ts snugly against the lip t" of the ring 6. A valvecontrolled pipe or conduit '81 connects the hopper 28 with the rear end of the dischar e chute 70. Durin drained'directly rom the hopper 28 into the latter through the pipe 81.

J ournaled in hangers 82 is a stub-shaft 83 on the inner end of which is mounted fast a bevel gear 84 which meshes with a bevel gear 85 fast upon the lengthwise extending shaft 17. By engaging a crankhandle 86 (-shown' injdotted lines in Fig. 2) with the outer end of the stub-shaft 83, the latter may be turned by hand power and the shafts n, z, 14 and 46 driven thereby in an emerathaw the slush may e- 88 is a short shaft 89 on the frontend of which is mounted fast a bevel gear 90 that meshes with the bevel gear e and on the rear end of which is keyed a bevel gear 91 that may, as hereinafter described, be thrown into and out of mesh with abevel gsar 92 fast on the lower end of the s aft n. Near the drivers seat 0'' is crume'dt on the chassis a a clutch-lever 93 which is connected with the upper end of a clutch-arm 94 b a link 95. The clutch-arm 94 is mounted e to swing on the chassis a and its forked lower end engages; the rooved hub of the bevel gear 91, which is, ree to slidelengthwise on the shaft 89,.be-

.ing keyed thereto. Hence by operating the clutch-lever 93 the engine ll may beconnected with and disconnected from the driving shaft n.

cated withinreach of the driver.

-The upper end of this clutch-lever 99' lo- I The engine at is shown conventionall as an internal combustion engine andthe eat from the waste gases or exhaust gases mg]: be utilized in melting the snow in the ta 68. To accomplish this purpose, the exhaust pipe 100 leads from the engine d into-the tank 68 and is formed into a coil 101 which surrounds the shell 52 ofthe triturator 53. The exhaust gases are finally discharged below the bottom of thetank at 102. The vehicle is provided with theusual steering-wheel 103 and steering mechanism 104, which are shown merely conventionally.

The casing f-is provided with supports or.

hangefel05 for the inlet-hose-plpeifq-and with hangers 76" on which rest extra section 7 6 of the discharge hose-pipe 6.

longest The operation of my new snow-destroying machine may be briefly described as follows: The driving shaft n is rotated by means of the water-wheel h or theengine d or by both these prime movers and in turn drives the conveyer-shaft a and the hollow shaft 14. The latter turns the cutter or disintegrator 4. Snow is shoveled by the'laborers into the hopper 28 and is fed by gravity through the 10 guard-rods u and the knives 7 to the cone veyerz. The guard-rods u serve to keep the knives 7 from contact with large pieces of stone or other hard substances which would be liable to injure them. The conveyer z carries the snow up to and forces it through the grating 37 In case pieces or other hard material pass through between the guard-rods u, the pressure exerted by the conveyer a will suflice to breakthem of stone, ice

into very small fragments, the ribs 38 of the grating 37 being edged on the face of the latter opposed to the conveyer a. The sweep 39 brushes the snow from the upper face of the grating 37 into the chute 2 and water flowing from the water-pipe 44 through the vanes a" on the arms of the water-wheel h.

The snow falls into the chamber i and is carried downward by the screw-conveyer 57, bywhi ch it is forced through the stationary grating 58. It is next subjected to the triturating action of the knives 64, 65 and is reduced practically to the form, of water. The water discharged from the water-wheel It will assist in the melting process. The liquid mass will overflow from the tank 68 and will flow down the helically-inclined surfaces 69 into the discharge chute 70, where the paddles or blades 7 2 will pulverize any lumps still remaining in the liquid mass, while at the same time these blades assist the movement of the latter toward the discharge end of the chute.

It is to be observed that, in my new snowdestroyer hereinbefore described, the liquefacient action upon the snow in the trituradisrupting action of the water with great force against the snow tor is the resultant of the disintegrating or ischarged and the triturating action of the knives which act upon the snow in the presence of the water which fills up the tank in which the triturator is mounted and into which it dis-' charges. The material which overflows the upper edge of the tank is that upon which the parts of the machine have acted the I prior to the overflow-and which is, therefore, the best prepared for discharge. Since the action of the knives of the triturator upon the snow takes place in the presence of an excess of water and, moreover, of water 1n motion, the snow is subjected to disintegration under the most favorable conditions for its rapid and thorough breakmg up and its discharge in a highly fluent state.
